I'm so sorry to hear that this happened to you. I've helped clean a place that had had fire go through. I couldn't believe where that smoke settled - (in the ice in the freezer).
I only ever use white vinegar as an air freshener and swear by it. It truly does remove odors. If you could spray the back of your fabric with a fine spray of vinegar then lay it out in the sun it would smell a lot better but you would need to get the smell out of your house before you bought your stash back in side. It sounds like a monumental job whichever way you go.
If it was me I think I'd be looking to the insurance company. I just hope your neighbours have insurance. You have enough pain to deal with as is.
Once again I'm so sorry this happened to you and hope you are able to find a fast solution.
